Module simple_extensions 

Available on crate feature parse only.

Rustic types for validating and working with Substrait simple extensions.

The raw YAML structs live in crate::text::simple_extensions. This module parses those values into the typed representations used by this crate:

• ExtensionFile – a fully validated extension document (URN plus its definitions).
• SimpleExtensions – the validated objects declared by a single extension file.
• CustomType / ConcreteType – type definitions and resolved type structures used when checking function signatures.
• Registry – a reusable lookup structure that stores validated extension files and exposes typed access to their contents.
